Thank you, so much for your help Fred_vdp! Many tasty internet cookies I'd bake for you if I could. I have installed the new drivers and I'll be attempting to play my game later today. For now, going to go watch Hotel Transylvania with my kids. I'll let you know how the game runs.
You saved me so much headache, I was kind of upset thinking the shop had played switcheroo and sold me a very old, very bad video card when I got the new one specifically to play Inquisition (my old one was a 4 thousand-something or other). Glad to see they hooked me up with something not so ancient, but still compatible with my 2010 computer.
*Edit* A little early to tell but installing new drivers seems to have helped the issue I think. Thanks, Fred_vdp!
